BACKGROUND

The study of the positional topographic anatomy of the lower poles of the thyroid gland (TG) will reduce the number of intraoperative complications during surgical interventions in this area, especially when using minimally invasive surgical access.

OBJECTIVE

To obtain information about the intravital positional anatomy of the lower poles of the thyroid gland in persons of both sexes with different body shapes.

MATERIAL AND METHODS

The research material was the data of anthropometric studies and the results of magnetic resonance imaging of the neck organs of 100 healthy volunteers (55 women — 55% and 45 men — 45%) The positional anatomy of the lower poles of the thyroid gland during flexion, extension and head turns was studied.

RESULTS

It was found that the location of the studied units of the thyroid gland in the frontal plane is not static and depends on gender, body type and position of the head and neck. It was revealed that the distance from the center of the jugular notch to the lower poles of the thyroid gland decreases with neck flexion in all studied groups. The distance on the right changes most significantly in the examined males with an ectomorphic body type (decrease by 44.2%), on the left — in the group of examined males with an endomorphic body type (decrease by 33.3%). Extending the neck and turning the head leads to an increase in the distance studied. Major changes were recorded when the head was turned to the contralateral side. For the lower pole of the right lobe, turning the head to the left in all groups of subjects leads to an increase in the studied variable. The maximum changes were recorded in the group of examined males with an endomorphic body type — 217.6%. For the lower pole of the left lobe, turning the head to the right also increases the value of this variable in all groups. Its maximum value was found in males with a mesomorphic body type — 110.4%.

CONCLUSIONS

The intravital positional anatomy of the lower poles of the thyroid gland has been studied and described, which significantly expands knowledge in the topographic anatomy of the organ.
